The Big Mac is considered a good candidate for the application of the law of one price and measurement of under or overvaluation of a currency. Develop an argument as to why this is a good idea

What will be an ideal response?

Answer: First, the product itself is nearly identical in each market. This is the result of product consistency, process excellence, and McDonald's brand image and pride. Second, and just as important, the product is a result of predominantly local materials and input costs. This means that its price in each country is representative of domestic costs and prices and not imported ones, which would be influenced by exchange rates themselves. The index, however, still possesses limitations. Big Macs cannot be traded across borders, and costs and prices are influenced by a variety of other factors in each country market, such as real estate rental rates and taxes.
